chunlee said:hi boy,
can u pls tell how to measure inductance and Q using network analyzer?
or send me some document about it?
Thanks.
sergio mariotti said:VNA may measure L (and or C) but it's poorly accurate, especially on the Q determination.
Qmeter, when used in conjunction with Standard inductances is the most accurate instrument.
Qmeter give L, Q, SRF.
I try to answer BigBoss and chunlee both.BigBoss said:sergio mariotti said:VNA may measure L (and or C) but it's poorly accurate, especially on the Q determination.

Why did you comment so ? When you short circuit of an inductance, you'll get "very accurately" R and X so then to find inductance value and its associated Q factor are not difficult.
Because in RF region, inductances and capacitances are not flat responded and in my opinion an inductance or capacitance should be measured at the frequency of operation (or closer to )
chunlee said:hi everyone,
I'm intend to measure my inductor on wafer at frequency around 2.4GHz. So i think the VNA is suitable for me. Can someone pls briefly tell me the procedure to characterize the inductor? (spiral and active inductor)
Thanks.
